Dry Braking

Braking Tradition

Once exclusive to the luxury car market, Electronic Parking Brakes (EPBs) are now more common within the mass market. Blue Print explores this opportunity, and what it means for the aftermarket.

With more vehicle manufacturers like VAG, Renault, Ford, BMW and Hyundai fitting electromagnetic handbrakes in recent years, the aftermarket is experiencing a growing interest in these components. In the world of independent garages, technicians are quickly realising that there are a number of differences in servicing and overhauling these braking systems.

OUT WITH THE OLD, IN WITH THE NEW

The twin cable and ratchet lever style of parking brakes were relatively straightforward to repair or replace in comparison to modern electromagnetic systems that are reliant on solenoids, sensors and calibration. Consequently, simple tasks such as pad and disc replacements now require the use of suitable diagnostic equipment that can activate the ECU to perform the wind-back and re-engagement process.

NECESSARY EXPERTISE TO AVOID A BAD SHOCK

As specific equipment is necessary for any jobs involving EPBs, it is often out of range for the average home mechanic. Technicians not only have to be cautious about inhaling brake dust and pressurised brake fluid escaping when working on calipers, they also have to be mindful of the risk of high amperage shock. The system may be 12V, but with a current draw of up to 20 Amps, there is enough electricity to make even the most seasoned engineer jump.

TOP TIP! It is advisable to connect a battery support unit as parking brake motors draw a lot of current (approximately 14-20 amps) when in use.

With this in mind, EPBs in the aftermarket create further opportunities for motor factors and well-equipped independent workshops to offer a service that was previously exclusive to vehicle dealerships.

All Blue Print brake discs are researched and manufactured in accordance with ECE R-90 regulations and OE. Furthermore, the brake disc range is balanced to minimise noise and vibration in order to ensure comfort. Precision casting and finish provides consistent quality and stable braking performance, allowing them to maintain their three-year unlimited mileage warranty against manufacturing defects.
